Pees in the brown Koolaid
The FedEx guy on my route has a new, hybrid-electric truck. I, on the other hand, bless my customers with a huge cloud of stinking diesel smoke when I back up to the dock. UPS really needs to consider jumping on the green bandwagon and powering its trucks with B20 biodiesel. I run biodiesel in my VW Jetta and it runs great, with no smelly exhaust. A B20 biodiesel blend would run just fine in any package car or feeder tractor with no modifications at all. Lets do it!
